Figure 1 shows the reprogrammable lock according to an embodiment of the invention, with all its details exploded. - The lock comprises a
stator 1, with a substantially hollow cylindrical shape, provided with anaxial hole 1a to contain arotor 2 in the form of a small cylinder that can rotate inside thestator 1. - In the inside surface of the
stator 1, inside thehole 1a,cavities 1c (four like opposed cavities) and 1b are defined, adapted to be used to house the members of the lock mounted in therotor 2 as will be described hereunder. - The
rotor 2 is composed of a cylindrical body wherein are formed cavities which contain the various members of the reprogramming mechanism of the lock. For this purposetransverse cavities 2b are formed on the side surface of therotor 2, adapted to receive respectivekey reading plates 3 andrespective springs 12 which bias thekey reading plates 3 radially outward. To be precise, a first group of fourkey reading plates 3 is inserted in a first row oftransverse slots 2b and a second group of fivekey reading plates 3 is inserted in a second row oftransverse slots 2a disposed in an opposite position to the first row. - Again in the lateral surface of the
rotor 2, near the ends thereof, twotransverse seats 2f are formed, adapted to houselateral inserts 6 withrespective springs 13 which bias thelateral inserts 6 radially outward. - Again in the lateral surface of the
rotor 2, between the two rows ofseats 2b, there is a row oftransverse seats 2a adapted to receiverespective locking plates 4. To be precise, ninelocking plates 4 are provided, that is to say a number equal to the number ofkey reading plates 3. Eachlocking plate 4 receives arespective programming plate 5 adapted to couple with a respectivekey reading plate 3, as will be described hereunder. - In the lateral surface of the
rotor 2, near the front end thereof, a lasttransverse cavity 2c is provided, which serves to contain arotation stopping plate 10 and the spring thereof 12 which biases it radially outward. - In the front part of the
rotor 2 there is a firstlongitudinal cavity 2d which serves to receive auser key 8 or aprogramming key 9, as will be described hereunder. - Again in the front part of the
rotor 2 there is a secondlongitudinal cavity 2e which serves for insertion of apin 7 which is used to join thelocking plates 4, theprogramming plates 5, thelateral inserts 6 and therespective springs 13 in a single body. - The
key reading plates 3 have ashaped cavity 3a with a protruding tooth 3c which serves for the passage and reading of thecoding profile keys - The outer part of each
key reading plate 3 hasteeth 3b which couple withmatching teeth 5a provided on the outer part of eachprogramming plate 5. In this manner, thekey reading plates 3 and theprogramming plates 5 form a single group, thus determining coding. Thekey reading plates 3 never protrude beyond the edge of the outer diameter of therotor 2, and their function is solely that of adapting to thecoding profile key rotor 2 with respect to thestator 1. - The bottom part of each
key reading plate 3 has anundercut seat 3d where therespective spring 12 is housed. - The
locking plates 4 have aseat 4a which serves to contain theprogramming plates 5. In thelocking plates 4 there is furthermore a slot or hole 4b which serves for passage of thepin 7. Thelocking plates 4 have one end which protrudes outward from therotor 2 entering into thecavity 1c of thestator 1 to block rotation of therotor 2 if an unauthorized person attempts to open the lock with a key with different coding from that of programming or use. - The
programming plates 5 haveteeth 5a which engage with theteeth 3b of thekey reading plates 3 which determine coding of the user key during programming. Theprogramming plates 5 have a slot orhole 5b to receive thepin 7 so as to form a single body integral with thelocking plates 4 and thelateral inserts 6. - The
lateral inserts 6 have anarched surface 6b adapted to slide on the inside surface of thestator 1. The inside surface of the stator acts as a cam, whereas thearched surface 6b of thelateral inserts 6 acts as a cam follower. - The
lateral inserts 6 further comprise ahole 6a for insertion of thepin 7 and another blind hole (not shown) which contains therespective springs 13. Thelateral inserts 6 thus serve to move theprogramming plates 5 integrally with thelocking plates 4. - The front
rotation stopping plates 10 have aseat 10a adapted to allow theuser key 8 or theprogramming key 9 to pass therein. The end of therotation stopping plate 10 protrudes from therotor 2 to engage partially in thecavity 1b of thestator 1 and block rotation of the rotor. Therotation stopping plate 10 is also used as an anti-picking plate, in that it is made of a material that withstands attempts at drilling or forcing with blunt instruments. In the outer part of therotation stopping plate 10 there is a relief cut 10b which provides a housing for thespring 12. - A
rotation limiter 11 consisting of a circular plate which has asquare hole 11a and atooth 11b is disposed in the rear part of therotor 2. Therotation limiter 11 is applied in the rear part of therotor 2 to limit rotation of the rotor during 90° opening of the lock. - In the front part of the
rotor 2 is disposed ahood 14 which has in its front part a cavity 14a destined to be disposed in register with thecavity 2d for passage of theuser key 8 or of theprogramming key 9. - The lock according to the invention is supplied with two
keys coding profiles programming key 9 and the other is theuser key 8. - The
programming key 9 differs from theuser key 8 in that it has twoteeth 9a and relative relief cuts formed at the end of the shank of thecoding plane 9b, at the shoulder of the key. Theteeth 9a of the programming key serve to operate therotation stopping plate 10, which is the first plate in therotor 2, in the direction of insertion of the key. - Operation of the lock according to the invention, which takes place by means of a sequence of operations, is described hereunder with reference to
Figures 2-7A . - The assembled lock, in the state in which it is supplied to the client, is as illustrated in
Figures 2 and2A . As shown inFigure 2 , therotation stopping plate 10 is locked in thecavity 1b of thestator 1, preventing rotation of therotor 2 with respect to thestator 1 in both a clockwise and a counterclockwise direction. Thelateral insert 6 is disposed in thecavity 1c of thestator 1 and prevents rotation of the rotor only in a counterclockwise direction. As shown inFigure 2A , theteeth 3b of thekey reading plates 3 are opposed to theteeth 5a of theprogramming plates 5, that is to say they are misaligned with respect to the grooves defined by theteeth 5a of theprogramming plates 5. - This condition is called the programming condition because in this position the lock must be programmed, giving the lock a missing characteristic, namely the ability to read only a key coding, so that it is used univocally by the owner of the programming key. From this position, the
special programming key 9 must be inserted into theslot 2d of therotor 2 in order to be able to programme the lock. - As shown in
Fig. 3 , once theprogramming key 9 has been inserted into the lock, theteeth 9a of theprogramming key 9 move therotation stopping plate 10 from thecavity 1b of thestator 1, so that thewhole rotor assembly 2 can subsequently rotate to the position in which programming has been accomplished, that is, 45° clockwise with reference to the figures. Before proceeding with rotation of therotor 2, it should be noted that therotor 2 is unable to rotate counterclockwise because of thelateral insert 6 which abuts against a plane of thecavity 1c of thestator 1, as shown inFigures 2 and 3 . - Furthermore, with insertion of the
programming key 9,Figure 3A thekey reading plates 3, thanks to the bias of the relative springs 12, come to rest on thecoding profile 9b of theprogramming key 9, correct alignment between theteeth 3b ofkey reading plates 3 and the grooves defined between theteeth 5a of theprogramming plates 5 thus taking place. - As shown in
Figure 4 , during programming (45° rotation of the rotor 2) thecurved surfaces 6b of the lateral inserts 6 slide along acurve 1d defined in the inner surface of thestator 1 which is eccentric to the axis of the lock. Consequently the lateral inserts 6 move towards the centre of therotor 2. - During this operation, the lateral inserts 6, by means of the
pin 7, pull the programming plates 5 (Figure 4A ) inserted in theseat 4a formed in thelocking plates 4, until they couple with thekey reading plates 3. In this manner, through meshing of theteeth key reading plates 3 and theprogramming plates 5, an integral assembly is created between thekey reading plates 3, thelocking plates 4 and theprogramming plates 5. - Once programming of the lock is completed, the
rotor 2 is unable to continue its rotation beyond 45°, in that, as shown inFigure 4 , therotation stopping plate 10 abuts against a plane of thecavity 1c present in thestator 1. - The next stage will be that of withdrawing the
programming key 9 and inserting theuser key 8 withcoding 8b identical to the previous one 9b. - As shown in
Figures 5 and5A , in the situation of the lock being closed without the key inserted, it is impossible for therotor 2 to make any type of rotation. In fact, therotation stopping plate 10 and thelocking plate 4, being part of the integral assembly ofplates springs 12, position themselves in thecavity 1c of thestator 1. -
Figures 6 and6A show the situation in which theuser key 8 is inserted in theslot 2d of the rotor. With reference toFigure 6A , during this operation thekey reading plates 3 rest on thecoding profile 8b of thekey 8. As a result the assembly ofplates rotor 2, so as to allow 180° rotation thereof, as shown inFigure 7A . - With reference to
Fig. 6 , in the same situation, therotation stopping plate 10, through thespring 12 which biases it, comes to rest on theuser key 8, which is lower in its working section than theprogramming key 9. Because of this therotation stopping plate 10 is caused to be moved towards the centre of therotor 2. - This causes alignment of the
rotation stopping plate 10 with therotor 2 in the upper part, whereas in the lower part therotation stopping plate 10 will abut against anouter wall 1e of one of thecavities 1c present in thestator 1. - In this condition the rotor can freely rotate 180°clockwise, as shown in
Figure 7 . - The rotation stop at 180° is formed at the shoulder of the
rotor 2 which abuts against a wall If of thecavity 1c. - In this position, called the "lock open" position, the
key 8 can be withdrawn. - It should be specified that withdrawal and insertion of the
keys locking plates 4 the possibility of being able to protrude from the line of the outside diameter of therotor 2. In fact thecodes key reading plates 3, integral with thelocking plates 4 and theprogramming plates 5. Thus during linear movement of thekey plates cavities 1c formed in thestator 1. - Moreover, when the
user key 8 inserted does not have the same coding as the programming key 9 (typical in attempts at breaking in with the use of forged keys) the no key situation described with reference toFigures 5 and5A is recreated. The differences in coding between the twokeys locking plates 4 are positioned inside thecavity 1c of thestator 1, thus preventing normal operation of the lock. - Numerous variations and modifications of detail within the reach of a person skilled in the art can be made to the present embodiment of the invention without thereby departing from the scope of the invention as set forth in the appended claims.
